CHECK-PUNCH.

SPECIFICATION forming part of Letters Patent No. .451,368, dated April28, 1891.

Applicationiiled January 27, 1891. Serial No. 379,259. (No model.)

To @ZZ whom it may concern,..-

Beit known that I, FRANK M. CLARK, of Tilton,in the county of Belknap,State of New Hampshire, have invented certain new and usefulImprovements in Check-Punches, of which the following is a descriptionsufficiently full, clear, and exact to enable any person skilled in theart or science to which.A

said invention appertains to make and use the same, reference being hadto the accompanying drawings,forming part of this specification, inwhich- Figure l is a side elevation of my improved checkpunch, and Fig.2 a front elevation of the saine, the base being shown in verticalsection taken on line m in Fig. 1.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My present invention is designed as an improvement on the device shownand described in United States Letters Patent No. 422,728, dated March4, 1890, and granted to lne for new and useful improvements incheckpunches, and relates especially to an i1nprove ment in the base ofthe punch, the object being to produce a more effective device.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation:

In the drawings,A represents the perforating mechanism considered as awhole, which is mounted on a cubical base C. As the construction andoperation of said mechanism are fully set forth in said Letters Patent,it is not deemed essential to particularly describe the same herein. Insuch construction much dificulty is experienced in inserting the checkor other paper sufficiently far under the plate d to enable thecutting-pins f to perforate it in the proper place. More particularly isthis the case with bonds or documents provided with series of detachablecoupons. My improvement overcomes this objection, and in carrying it outI make use of the following means: A tubular vor cylindrical chamber gis formed horizontally in the base C and is open at both ends. Thecentral line of said chamber is slightly at the rear of theperforating-pins f. An opening 72, is formed in the top wall of thechamber directly under the pins f, and the bed die or plate t' isdisposed across the mouth of said chamber. At the rear of the diet' thebase is slotted longitudinally at 7c, said slot inclining downward andopening into the chamber g. The adjustable gage-plates m have theirfront edges iush with said slot and are turned upward at p, the toesthus formed serving as a straight edge for placing the sheet or check Din proper line under the punch and to direct an edge of said sheet intothe slot.

In the use of myimprovement the check D is disposed on the upper face ofthe base and passing under the cutting-pins f, its inner edge enteringthe slot lt. Said pins are forced therethrough into the bed-die t' bythe plunger-disk t, perforating the check in the usual manner. It willbe seen that by employing the cylindrical chamber g the check may bepassed any desired distance under the punch, the shape of said chambercausing it to roll or curl therein, as shown in Fig. l. The chamberbeing open at the ends the check may be quickly removed by sliding itlongitudinally thereof.

Having thus explained my invention, what I claim isl. In a check-punchof the character described, the combination, with the perforatingmechanism, of a base supporting said mechanism, a tubular chamberopening through said base, and an inclined slot opening into saidchamber at the rear of the perforating-pins of said mechanism,substantially as and for the purpose set forth.

2; In a check-punch of the character described, a base provided with atubular chamber, a vertical opening under the bed-die in the top wall ofsaid chamber, and an inclined slot leading into said chamber at the rearof said die, substantially as and for the purpose set forth.

3. In a check-punch of the character described, a base provided with atubular chamber, and an inclined slot opening into said chamber at therear of the cutting-pins, in
